Top Hammer Drill Bits mine drilling bit adopt high quality steel
and tungsten carbide to ensure product quality. With superior wear
resistance and impact toughness, our button drill bit is very
popular at home and abroad.

1.Comparing with tapered chisel bits and tapered cross bits, button
bits has higher technology, much longer primary drilling time and
higher drilling efficiency, so that the button bit is popular among
the users.

2.Tapered equipment affords drillers the ability to change drilling
bits whilst still using the same drilling rod. Drillers choose
tapered button bits for faster drilling penetration rate. Different
taper sizes have different characteristics when it comes to the
“knock-off” index – the smaller angle will prevent the bit from
spinning.

3. Suitable for small hole range• Widely used in Dimensional Stone Quarrying Industry• Widely used in Underground Mining Industry

Widely used in mines, quarries, earthworks and other engineering
drilling blasting hole, guardrail hole,mountain reinforcement, anchorage and other engineering holes,
geothermal exploration hole, Well bore and other fields.
